PUMP.

SPECIFICATION forming part of Letters Patent No. 285,402, datedSeptember 25, 1883.

Application filed April 24, 1883. (No model.)

To all whom it may concern:

Be it known that we, ALEXANDER Fyrn and- THOMAS RAwsoN, of Paterson, inthe county of Passaic and State of New Jersey, have invented a new anduseful Improvement in Pumps, of which the following .is a specification.

The present invention relates to that class of pumps adapted for drawingale, beer, and other liquors or liquids of any kind from casks or otherreceptacles; and its main object is to provide a construction by whichseveral different kinds of liquors or liquids can be drawn successivelyfrom different c'asks or reservoirs when connected with the pump, and bywhich the parts of the pump which are common to the different kinds ofliquors can be cleansed of the liquor last drawn before a different kindis admitted.

The invention consists in the combination, with ,a chamber or receivercommunicating with the pump and supplied with several pipes, eachprovided with a cock and connected with different liquor-reservoirs, ofmeans for supplying air or water to the parts common to the differentkinds of liquors, for the purpose of expelling any liquor therefrombefore a different kind is admitted, also, a chamber or receivercommunicating with the exhaust of the pump, and provided with two ormore pipes or branches, each furnished with a cock, and adapted to beconnected with different reservoirs of liquors, in combination with apipe provided with a cock or valve, for the purpose of supplying air orwater to the parts of the pump common to the different liquors, allsubstantially as hereinafter set forth and claimed.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a view in elevation of the pump and its attachments. Fig. 2.is a vertical section of the common chamber, showing also one of theconnected branches with its cock and the air-pipe; and Fig. 3isahorizontal section of such chamber and its branch pipes through theline or m of Fig. 1.

I11 the drawings, A represents the pump proper, which may be of anyordinary construction and operation adapted to draw fluid from a lowerlevel and deliver it from a discharge-cock, B.

tion with the exhaust of the pump.

D is a pipe by which the chamber 0 and the exhaust of the pump areconnected.

a, b, '0, and d arepipes or branches to which pipes may be attachedleading into and attached to the common chamber 0, and conneoted with oradapted to be connected with casks or reservoirs containing liquors,each pipe being connected with a different cask or supply of liquor.Each of the pipes open j ing into the common chamber, 0, is providedwith a cock, f, preferably located near the chamber 0, so as to bewithin convenient reach, and by opening or closing the cooks fcommunication can be made at will between the chamber 0 and any one ofthe liquor supplies to which any of the pipes is connected, and can becut off as to all the other supplies, while by closing all of the cooksf the communication between the chamber 0 and all the liquor supplieswill be cut off.

E is a pipe leadinginto the chamber 0, preferably near the bottomthereof, and opening into the air, and it is provided with a cock, 0,for making or cutting off communication with the air. The upper part ofthis air-pipe is preferably curved, as shown in the drawings, forconvenience of immersing its open end in'a vessel of water held in onehand while the handle of the pump is operated by the other hand, for thepurpose hereinafter described.

The pump and its attachments may be secured toa metal or wooden frame inany of the ordinary ways, and may then be screwed to the wall or beneaththe counter, or in such other position as will renderit convenient foruse.

The operation of the pump and its attachfollows: The pipes leading fromthe different liquor supplies should be numbered or labeled, so that theoperator may know at a glance which of the cooks f to open or close inany given case. kind of liquor-as beer, for instanceall the cooks fexcept the one in the pipe leading from the beer-cask, are closed, whilethat one is opened. The pump is then worked and the required quantity ofbeer is drawn into the cham- O is a chamber or receiver incommunicaments, as above described, briefly stated, is as y If it isdesired to draw any special IOI) ber 0 through the pump and thedischarge-cock 13. During the pumping the cock 6 in the pipe E is ofcourse closed. If it is next desired to draw some other kind of liquorand to have the same pure and uncontaminated by reason of the beer orother liquor last drawn, some portion of which will necessarily be leftin the chamber 0 and the body of the pump, all the cooks f are closedand the cocksand B are opened, and the pump is then worked. A strongcurrent of air will thus be drawn into and through the pipe E, thechamber 0, and pump A, and will be discharged from the cock B, by which,with a few strokes of the piston, the last vestige or trace of liquorwill be expelled from these parts, and they will be thoroughly cleanedto receive a different liquor. \Vhenever it is desired to wash out theparts of the pump, which are common to the different kinds of liquors,the downwardly curved mouth or end of the pipe E may be placed in avessel of water or other cleansing-liquid, and by working the pump suchliquid will be forced through these parts to produce the desired result.

It is observed that the main. office of the chamberO is to afford acommon receptacle or receiver for the different kinds of liquors locatedbelow and connected with the exhaust of the pump; and the invention isnot limited the various reservoirs may be connected to a larger pipe ortube, which will constitute the chamber or receiver, and which in turnmay be connected with the pump A by a pipe, D; or, in case a chamberlike the chamber 0 is used, it may be screwed, capped, or otherwisesecured directly to the bottom of the pump below its valve-seat.

\Vhat is claimed as new is 1. In a pump for drawing ale, beer, or otherliquors or liquids, a chamber or receiver communicating with thepump-exhaust, and provided with two or more pipes or branches, eachfurnished with a cock and adapted to be connected with differentreservoirs of liquor, in combination with means for supplying air orwater to the parts of the pump common to the different liquors,substantially as and for the purpose described.

2. In a pump for drawing ale, beer, or other liquors or liquids, achamber or receiver communicatin g with the exhaust of the pump, andprovided with two or more pipes or branches, each furnished with a cockand adapted to be connected with different reservoirs of liquor, incombination with a pipe, E, provided with a cock or valve, 6, forsupplying air or water to the parts of the pump which are common to thedifferent liquors, substantially as and for the purpose described.
